Quantity

AGW Series air compressor/generator/welder combo, one gasoline engine driving all three functions. The 20-gallon Honda model is a genuinely larger tier, nearly double the compressor output, welder amperage range, and price of the 30-gallon/base-mount Mi-T-M or Vanguard models. Honda and Vanguard engines are 49-state, not sold in California; Mi-T-M has no restriction.

Shipping & Freight

For an order containing products from a single brand, shipping is a flat rate based on your order total:

Orders up to $5,000: $279
Orders $5,000 to $10,000: $347
Orders $10,000 and over: $517

These rates cover standard freight delivery to a commercial address. After you place your order, our team will confirm your delivery timeline within 1 to 3 business days.

Ordering from more than one brand? Multi-brand orders ship on separate freight and are quoted individually rather than at the flat rate above. Place your order or contact us first and we will confirm total freight before anything is finalized.

Liftgate service is not included in these rates. If your delivery location has no loading dock or forklift to unload the freight from the truck, liftgate service is required and will be added to your shipping charge. If you are unsure whether you need it, contact us before ordering.

Commercial delivery locations are preferred when available. Residential delivery, limited-access locations, and appointment scheduling may affect handling.

Lead times vary by product, manufacturer availability, and selected options. Some configured, special-order, or non-stock items require additional processing time before they ship.

Please inspect all freight shipments at delivery before signing. If you see visible damage, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before you purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition. Special-order, custom-configured, used, damaged, or installed items may not be eligible for return.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

Mi-T-M's AGW Series combines an air compressor, generator, and welder into one gasoline-engine-driven unit, built for a crew that needs all three functions on a service truck or trailer without carrying separate machines. The line splits into two real tiers, not just a size choice: the 20-gallon Honda-engine model delivers nearly double the compressor CFM, welder amperage range, and price of the 30-gallon or base-mount Mi-T-M or Vanguard models, which are otherwise the smaller, lower-output configuration.

Generator and welder draw from the same engine but operate as distinct modes: Generator Mode runs AC current only, with the idle-down feature enabled and the switch set to full throttle; Welder Mode runs DC current only and requires the engine at full throttle with the selector switch set accordingly. Three engines are available: Honda (20-gallon model only), Mi-T-M, and Vanguard (the latter two each offered as a 30-gallon tank or tankless base-mount). Honda and Vanguard are both 49-state engines not sold in California; the Mi-T-M engine carries no such restriction.

Common Applications

Field welding, air tool operation, and portable power from one machine on a service truck or trailer
Utility, fence, and service-truck work where a crew needs to weld, run air tools, and power electronics without hauling three separate machines

Selection Notes

The 20-gallon Honda model is a genuinely different tier, not a size pick: nearly double the CFM, welder amperage range, and price of the Mi-T-M/Vanguard models
Honda and Vanguard engines are both 49-state and not for sale in California; only the Mi-T-M engine has no restriction
Mount choice (30-gallon tank or tankless base-mount) is available on Mi-T-M and Vanguard engines; the Honda model is 20-gallon tank only, no base-mount option
Generator output holds flat at 4500 watts regardless of compressor load on the Honda model, but drops from 3000 to 2500 watts under compressor load on the Mi-T-M/Vanguard models

Compressor: 30.5 CFM @ 90 PSI / 29.0 CFM @ 175 PSI on Honda model; 16.4 CFM @ 90 PSI / 15.7 CFM @ 175 PSI on Mi-T-M/Vanguard models; 150-PSI maximum rated regulator
